search session message content

[tulsi-builder]

Category: new-feature
User Impact: Users can search chat sessions by message content from Session History and the sidebar, then jump directly to the matching message.
Problem: Goose2 only searched session metadata, so people could not reliably recover a past conversation when the remembered detail lived inside the chat body. Search results also needed to keep Goose2-local titles, persona/project metadata, and archive filtering instead of trusting exported session metadata.
Solution: This adds a backend-assisted message search path that scans exported session content while leaving display metadata in the frontend session store. Session History and the sidebar each manage their own submit-on-Enter search state, merge message matches with existing metadata matches, and open sessions at the matched message with a fallback scroll target when replayed message IDs differ.

1. Open Session History and search for a phrase that appears only in a past message, then press Enter.
2. Confirm the results show snippets and message match counts, and clicking one opens the session and scrolls to the matched message.
3. Open the sidebar, run a different search, and confirm its query and results stay scoped to the sidebar.
4. Search for a term with no matches and confirm both surfaces show explicit empty states instead of the normal session list.
